Location and accuracy The location of this prospect is uncertain. It is known only from a small map in Wright and Wright (1908) that is nearly impossible to reconcile with modern topographic maps. For this record, the site is about 4.9 miles west of the mouth of the creek that enters the west end of Salmon Lake. It is at an elevation of about 2,000 feet, about 0.5 mile west-northwest of the center of section 34, T. 72 S., R. 82 E. The actual location of the prospect, however, may be several miles or more from this site.

Geologic setting

Geologic description

This deposit consists of a quartz vein containing pyrite, chalcopyrite, galena, and sphalerite (Wright and Wright, 1908). The vein is 6 inches to 4 feet wide, strikes N65W, and dips 60 W to vertical. It cuts gabbro and amphibolite that may be part of a large Cretaceous intrusion near Pin Peak (Eberlein and others, 1983; Brew, 1996). A tunnel at an elevation of about 2,000 feet is 130 feet long.
